To all whom it may concern: 7

Be it known that I, ARTHUR NtlAL KERR, a resident of Pittsburgh in the county of Allegheny and State of Fennsylvania, ave

invented a new and useful Improvement in Cylinder-Cars, of which specification. I

The invention relates to cylinder cars and more particularly to cylinder cars for transporting liquids having high vapor tension.

The demand for gasolene has resulted in the production of very light gasolene called casing head gasolenes o rnaphthas which are condensed from natural gas. Some of these casing head gasolenes or naphthas and particularly the lighter portions revaporated from thecasing head gasoleneaafter it is made, have a very high vapo'r tension and pressure is necessary to maintain the vapor 1n li uid form. It is estimated that from one-t ird to one-half of the liquefied va-' por made at casing head gasolene plants reva orizes andreturns to gaseous form.

1 he ordinary tank car used for transporti'ng liquids is unsuitable for transporting these high vapor, tension liquids, and is, in

the following is a fact, unsafe and its use is not allowed? It has therefore been necessary to devise special means for transporting these wild or hlgh vapor tension gasolenes and tothis end the present invention has been devised.

The general object of the invention is to provide a car in which liquids having a high vapo r tension may be safely transported.

Another object is to provide a doubly safe container for shipping fresh, wild, or high vapor tension casing head gasolene or liquefied vaporwhich has evaporated from casing head gasolene and been condensed and reliquefied one or more times. 1

Another object is to rovide a suitable car in which either smal or large quantities of liquid having high vapor tension may be safely transported.

Other objects and advantages of the invention will appear from the following Specification.

ing the manner of connecting one ofthe units to a supporting member.

e car comprises an exterior shell or,

casing 1 preferably ofcylindrical shape and formed of sheet metal and having its ends closed by the heads 5 and 6, the latter con taining a plurality of openings 7 which are tightly closed by manhole covers. 8. The 65 I shell is provided with the usual extension 9 on 1ts top in which is located a standard manhole opening normally closed by a cover 10. A suitable safety valve 11 is connected with the extension 9 for relieving pre's- 7 sure Within the tank when it exceeds the usual amount. The shell is also provided WIth the usual valve,-eontrolled drainage openlng or leg 13 through which liquid can be withdrawn. This shell forms a liquid and gas-tight container.

Within the shell and suitably secured thereto, such as by riveting, otherwlse, are two or more diaphragms or auxiliary heads, each provided with a plurality of openings 14 in which are held a series of liquid containing units 2, each having oneof its ends provided with filling valves accessible through one of the openings '7 in the head of the shell. The openwelding, or I ings 14 are so spaced in the diaphragms 4% that the units. 2 are efficiently distributed throughout the interior of the shell.

\ eted, welded or otherwise fastened theretoa pair of lugs 15 shown in detail in Fig. 4, the bent-up portions of which have openings registering with openings in the auxiliarhead 4. The lugs are fastened to the auxi iary head by means of bolts passing through An embodiment of the invention is illus-i the openings. Any other suitable fastening trated in the accompanying drawings in which Figurel is a side elevation of the car with a portion of the shell broken away to show the interior; Fig. 2 is in part anend elevation and in part a transverse section means may be employed for securely holding the tubular-units within the auxiliary heads to prevent longitudinal movement of such uni i Each tubular unit is closed by a head 16- The tubular units 2 are preferably of cy- These valves may be of any suitable type, those illustrated being of the type known be Y convenient as ueller valves. For the purpose of, protecting .thesevalves, the heads 16 are ositioned within the ends of the tubes sot at the'valves are housed within thetube and do not project beyond it." There is thus no danger of breaking, bending or otherwise damaging the valves in the handling of the tubes or in case the tubes break down under end shocks on the car. Two valves are emloyed'so that the tubes ma be conveniently lled by attaching a flexi le plpe from a 2w liquid sup ly to one end of them,-and open'- ing the ot or to permit the escape of air from the tube and also so that they may ly emptied by attaching a source of pressure to theupper valve and valve.

forcing the liquid outthrough the lower The ear may be readily manufactured and assembled by forming the metal shell in the usual manner and mounting the auxiliary heads therein. The tubular units may be manufactured in uniform sizes and. 'then inserted in the shell: and fixed n the auxiliary heads. The capacity of any tank car' may be varied by varying the number of units within it, and cars of large orsmall capacity may be built without reuiring any variation in the structure of t e tubular units. The im ortance of this flexibility, from a manu acturing standpoint, will be readil appreciated. The construction is equal y as important for purposes of repair, because any one of the units ma be removed andquickly-re laced by anot er and then re aired ateisure without interfering with t e use of the ca r. It is very rare that more than" one unit s I out of repair at one time, and incase the car is not near a supply of units, such unit can be removed wit out seriously lessening the usefulness of the car as a whole. In

; other. words, the" structure cannot only be 'to one ofthe ,units does not materially crease the usefulness of the car even if're- 6 inexpensively manufactured by reason of the standardization of the units and the possibility of variation in tank capacitiesy a simple variation in the number of units, but also it is such that a continuous usefulness of the car is insured. Damage pairs to that unit cannot be immediately made.

Furthermore, the structure possesses the advantage th t it isdoubly safe for transporting liqui s of high vapor tension. Each. of the tabularunits by reason of its limited ho d 'the liquid safely ing transportation.

lights in the switch ca acity can be made sufliciently stron to under pressure urf, for any cause, one

of these tubular units should become damaged, the leaka e of the liquid therefrom would neverthe ess 'not endanger the car because the liquid and vapor would be held safely within the outer shell and if the pressure became excessive, such pressure would be vented through the relief valve. On the other hand, if these tubular units were shi ped in a box car and one of them should eak, the ,vapor which is heavier than air would roll out from the box car at the level of the floor, which isabout the same height from the ground as the switch lights in a railway switch yard. There would be, therefore, great danger of the whole box car becomin ignited and the other tubes exploded. ith the present invention, however, if one of the tubes should leak, the liquid and vapor are retained within the shell,'and under ordinary conditions would not leak outside of it.

If the pressure should become excessive, the

' vapor would be vented through the relief" of the shell and it would before reachin r the switch ard. I the vapor valve on the to become scatter should become ignite it would'burn at the top of the metal shell instead of at the ,bottom of a box car as would be the case if the tubes were transported in such a' car.- ,It is to be understood that the structure shown is for purposes of illustrationonly,

andthat variations may be made therein which come within the spirit and scope of the appended claims.
